Abstract

Drought has emerged as a critical issue in Tangerang Regency, Banten Province, primarily driven by the prolonged dry season, declining rainfall, and rising temperatures above average, all of which are exacerbated by the El Niño phenomenon. These conditions pose serious threats, including water shortages, reduced agricultural productivity, and the potential for widespread drought if left unaddressed. This study aims to map drought threat levels at the sub-district scale based on rainfall and temperature parameters. The integration of these two variables is essential, as drought is influenced not only by insufficient rainfall but also by elevated temperatures. Thus, a multivariable approach offers a more comprehensive and accurate spatial assessment. The analysis applied in this study involves scoring and overlay techniques for each contributing parameter. The results identify areas with varying degrees of drought threat—low, light, moderate, high, and extreme. Notably, 27.63% of the regency is classified under extreme drought risk, predominantly in the central to southern regions, due to the combination of very low rainfall and very high temperatures. The resulting drought threat map serves as a crucial reference for local governments, farmers, and the Regional Disaster Management Agency (BPBD) in planning effective mitigation strategies, early warning systems, and sustainable water resource management.

Abstract

This study aimed to develop and validate a Higher-Order Thinking Skills (HOTS) assessment instrument that leverages Wordwall activities embedded in Google Sites for teaching Newton’s Laws. A quantitative-descriptive design with an evaluative approach was employed. Nineteen Grade XI science students from Gajah Mada Private Senior High School were selected through purposive sampling. Item analysis examined validity, reliability, difficulty level, and discrimination power. Of the ten multiple-choice items constructed, five (50 %) met validity criteria, and the instrument achieved a reliability coefficient of 0.492, indicating adequate internal consistency. Difficulty indices classified three items as difficult and seven as moderate, while discrimination indices categorized two items as very good, three as good, one as fair, and four as poor. Students’ mean achievement score of 37.89 % suggests limited familiarity with HOTS-oriented questions. Pedagogically, embedding Wordwall in Google Sites enhanced learner engagement, reduced test anxiety, increased comfort, and simplified teachers’ post-test analysis through automated scoring. Consequently, the HOTS-based instrument is not only statistically sound but also practically effective for supporting digital physics instruction.

Abstract

This study aims to develop a Guided Inquiry-Based Student Worksheet (LKPD) assisted by Assemblr Edu to improve students’ conceptual understanding in an Electronics course. The LKPD is designed to engage students in structured investigative learning through the guided inquiry approach, while Assemblr Edu serves as a visualization tool for displaying 3D representations of equipment, materials, and electronic circuits used in learning activities. The study follows the ADDIE development model (Analysis, Design, Development, Implementation, and Evaluation), but is limited to the development phase. Data were collected through expert validation sheets and student perception questionnaires. The content and media experts each provided a validation score of 95%, categorizing the LKPD as “highly valid” for field testing. Furthermore, the student perception analysis yielded a favorable score of 92.3%, indicating strong acceptance of the product in terms of design, content clarity, and learning motivation. These results confirm that the developed LKPD is both pedagogically and technologically suitable for use in higher education, particularly in supporting students’ conceptual understanding of complex topics such as RC and RLC series circuits in alternating current (AC). The integration of guided inquiry with augmented reality enhances student engagement and allows for better conceptual visualization, making it a promising tool for improving the quality of Electronics instruction.

Abstract

Physics learning is often perceived as challenging by students due to the abundance of formulas and abstract theories, as well as the lack of contextual learning resources. One approach that can be implemented to enhance students' interest and understanding is integrating local wisdom into physics learning through ethnophysics. This study aims to identify physics concepts in the Sigale-Gale puppet performance in North Sumatra and to analyze how the ethnophysical approach can be utilized to create more contextual and meaningful learning experiences. This research serves as an initial study of North Sumatran cultural performances in the context of physics. The method used is qualitative, in the form of a literature review. The results indicate that the Sigale-Gale performance encompasses various physics concepts, such as sound waves produced by gondang musical instruments, and the principles of motion, levers, balance, and acceleration embedded in the puppet’s mechanism. By applying the ethnophysical approach, students can gain a more tangible understanding of physics while also helping to preserve local culture. These findings can serve as a foundation for developing lesson plans (RPP) based on local culture, making physics learning more enjoyable, interactive, and meaningful.

Abstract

Persistent misconceptions about temperature and heat often undermine students’ progress in thermodynamics.  This study therefore analysed Grade-11 learners’ conceptual understanding of these topics using a Four-Tier Multiple-Choice Diagnostic Test, an instrument that registers answer correctness, explanatory reasoning, and confidence on both selections.  A descriptive quantitative design was adopted.  Thirty students from class XI-34 of SMAN 3 Medan completed a five-item test that had been validated by experts and piloted for clarity; psychometric checks on the study sample confirmed good reliability (Cronbach’s α = 0.88) and adequate item validity (four of five items met the r-table criterion).  Responses were coded into four epistemic categories—Understands Concept (UC), Lacks Knowledge (LK), Misconception (MC), and Error (E)—and analysed. Findings show that overall achievement averaged 30 %, with individual scores ranging from 0 % to 80 %.  Across the entire data set, only 27.3 % of responses were classified as UC, while 19.8 % fell into LK, 45.3 % into MC, and 8.0 % into E.  Item-level analysis revealed that the highest misconception rate (73.3 %) occurred on the question concerning the effect of temperature on objects, whereas the phase-change item yielded the strongest understanding (46.7 % UC, 20 % MC).  These results confirm that misconceptions—especially the conflation of heat with temperature—constitute the principal barrier to coherent learning in this cohort. The study underscores the diagnostic power of four-tier instruments and recommends their wider use across other physics domains, enabling teachers to design confidence-sensitive interventions that directly target high-certainty errors and reinforce fragile correct ideas.

Abstract

The declining academic participation and study persistence among Indigenous Papuan students at Universitas Musamus highlight a critical issue that demands thorough investigation. While various external factors have been previously examined, this study specifically focuses on internal learning barriers, which remain underexplored in the context of higher education in Papua. The aim of this research is to explore key internal constraints affecting students' academic engagement, including motivation, comprehension of course materials, learning strategies, and personal or social disruptions. Employing a qualitative case study approach and Miles and Huberman’s interactive data analysis model, data were collected through open-ended questionnaires and semi-structured interviews with Indigenous Papuan students. The findings reveal a complex interplay of internal challenges such as low motivation, self-doubt, ineffective learning approaches, and physical or psychological discomforts that hinder students’ learning processes. These internal barriers not only reduce classroom engagement but also negatively impact students’ perseverance in completing their studies. The study underscores the urgent need for contextually responsive and sustained institutional support, such as academic and psychosocial mentoring programs, to foster holistic success among Indigenous Papuan university students.

Abstract

Active learning should involve students directly in the learning process through interaction with peers and teachers. However, classroom instruction often fails to engage students effectively, with limited use of varied instructional media and models. This study aims to develop a Respiratory Card learning medium using the Project-Based Learning (PjBL) model to improve learning outcomes of fifth-grade elementary school students on the topic of the human respiratory system. This research employed a Research and Development (R&D) approach using the 4D development model, which includes the stages of Define, Design, Develop, and Disseminate. Data collection techniques included interviews, observations, questionnaires, and tests, while data were analyzed qualitatively and quantitatively. The results showed that: (1) the Respiratory Card learning media was declared valid with average scores of 88% from content experts and 90.6% from media experts, categorized as “highly feasible” using a Likert scale; (2) the media was considered practical based on a 92% average score from teacher responses, categorized as “very practical”; and (3) the media was effective, as indicated by an improvement in students’ test scores to an average of 84.2% at SDS Attaufiq Medan, and significant differences were found in learning outcomes between the experimental and control classes at UPT SDN Percobaan (sig. value = 0.000 < 0.05). The use of the Respiratory Card media enhanced student engagement and improved learning outcomes.

Abstract

This study aims to examine the physics concepts embedded in the traditional Indonesian games Tarik Tambang (Tug of War) and Balap Karung (Sack Race) through the application of Newton’s Laws. Conducted within the framework of ethnophysics, the research seeks to bridge scientific principles with local wisdom to foster contextual and engaging physics learning for students. A qualitative approach utilizing literature review was employed, analyzing various scholarly sources related to traditional games and their underlying physical principles. The findings reveal that Tarik Tambang illustrates Newton’s Second Law of Motion and the role of static friction. The game demonstrates how the acceleration of the opposing team is determined by the net pulling force and total system mass, while static friction is essential for maintaining player balance and traction. Additionally, strategies such as placing heavier players at the back enhance force generation and overall team performance. In Balap Karung, Newton’s Third Law and momentum significantly influence participants’ movements. The forward propulsion results from the backward action force exerted by the feet, which is met with an equal and opposite ground reaction force. Momentum affects the stability and speed of the jump, and friction between the sack and ground determines the efficiency of motion. This research highlights the pedagogical potential of traditional games in physics education. By contextualizing Newtonian mechanics through culturally familiar activities, students can develop a more concrete understanding of physical laws. The study recommends incorporating such games into instructional strategies to promote meaningful and culturally responsive science learning.
